New surveillance system can compare your face against 36 million others in a single second

Brave New World.

Using facial recognition to process surveillance footage isn't a new concept — Scotland Yard began using the technique in the wake of last year's London riots — but a new system developed by Hitachi Kokusai Electric could make the process quicker and more flexible than ever before. Shown off at this year's Security Show expo in Japan, the system processes footage from both still images and live footage, recognizing faces in real-time, and can search through up to 36 million different faces for a comparison in one second. Recognized faces are displayed as thumbnails and grouped with matching footage, allowing the operator to look at all of the actions of a given person immediately.
